The Archdiocese of Tarragona (Latin: Archidioecesis Tarraconensis) is a Latin Church ecclesiastical territory located in north-eastern Spain, in the province of Tarragona, part of the autonomous community of Catalonia. The incumbent Metropolitan Archbishop also bears the title Primate of Spain and heads the ecclesiastical province of Tarragona, having Metropolitan authority over the suffragan dioceses of Girona, Lleida, Solsona, Tortosa, Urgell and Vic.
The archdiocese, created in Roman times, was reestablished in 1118 after the Muslim occupation.
